Yeah it definitely is necessary, you’ll notice a better difference with the higher output but I will say if you got chipping and bad paint issues it’s gonna eat it right up
For effective car washing, flow rate is as if not more important than pressure. Generally for car washing you would want your psi in the 900-1000 psi. However I believe this unit has a max flow rate of 1.0gpm (most likely measured at no pressure) which is much too low. I guess this fits in the better than nothing category, but I would not buy this specifically for washing your car.
Exactly ! Why spend money on such useless junk like this when a water/garden hose will work far much better. And you don't have to worry about moving the bucket all over the place with you. Smh, some people find an excuse to buy anything, or reason with trash
Why is dewalt always better? I can name a few dozen products from Ryobi that are better price value for money then dewalt by miles . Dewalt specialises in construction for trades where as Ryobi is more of a diy. And what you doing now is nothing more then a diy. 😂
